a homage to your phrase of the week,
Loose lips sink ships is an American English idiom meaning "beware of unguarded talk". The phrase originated on propaganda posters during World War II.[3] The phrase was created by the War Advertising Council[4] and used on posters by the United States Office of War Information.[3]
This type of poster was part of a general campaign of American propaganda during World War II to advise servicemen and other citizens to avoid careless talk that might undermine the war effort. There were many similar such slogans, but "Loose lips sink ships" remained in the American idiom for the remainder of the century and into the next, usually as an admonition to avoid careless talk in general.[5][6][7] (The British equivalent used "Careless Talk Costs Lives", and variations on the phrase "Keep mum",[8] while in neutral Sweden the State Information Board promoted the wordplay "en svensk tiger" (the Swedish word "tiger" means both "tiger" and "keeping silent"), and Germany used "Schäm Dich, Schwätzer!" (English: "Shame on you, blabbermouth!")).[9]
